HEATING-sTovE.

- SPECIFICATION forming part of Letters Patent No. 297,902, dated April 29, 1884.

Application led June 7,' 1883. (No model.)

To a/ZZ whom it may concern:

Be it known that I, WILLIAM A. WINFREE, of Elizabethton, in the county of Garter and State of Tennessee, have invented a new and Improved Heating-Stove, of which the following'is a full, clear, and exact description.

The object of my invention is to furnish a heating-stove that will consume the smoke from the fire, thereby effecting a saving of fuel and increasing the heating capacity of the stove. g

My invention consists in a stove composed of an inner and an outer cylinder, the space between the two cylinders being divided by an inclined ange, so that the smoke and other products of combustion are distributed between the two cylinders and vcaused to traverse over an extensive heating-surface before passing to the flue, as hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification,

in which similar letters of reference indicate corresponding parts in both figures.

Figure 1 is a vertical section of a heatingstove of my improved construction. Fig. 2 is a horizontalsection on the line xx, Fig. 1.

A is the base of the stove, which may be of any suitable character, and is provided with an ordinary grate, c.

B is the inner cylinder and combustion chamber, preferably formed of cast metal, and fitted with a removable top or cover, b, that is to be' removed when the stove is to be supplied with fuel.

C is the outer cylinder, preferably made of sheet metal, and formed with an extended top portion,d, tting closely to a flange formed at the top of the inner cylinder, B.

e is a flange formed upon the exterior surface of the inner cylinder, B, and extending at opposite sides from the lower part of the cylinder to near the top, so as to form an up-` per and lower space between the two cylinders, the lower space, f, being for the products Vof combustion, and the upper space, f', being an airchamber, to which fresh air is admitted through the openings c. Beneath the iange, at its upper portion, on one side, the inner cylinder is formed with an outlet, g, to allow the products of combustion to escape into the lower space between the two cylinders, and

at\the opposite side is the escape-hue h, by which the products of combustion finally escape. In the enlarged upper portion, d, of the outer cylinder are openings fi, that allow escape of the heated air from the upper space. By this construction the smoke from the fire is caused to pass downward between the two cylinders, and then upward again before it 6o reaches the escape-hue, and it is thus distributed in a thin stream over the surface of the inner cylinder, which, being highly heated, causes the combustion of the smoke before it finally escapes. At the same time the outer cylinder becomes highly heated and furnishes a large extent of heating-surface. This stove `is well adapted for use on railroad-cars.

.At k in the outer cylinder is a door, through which ashes may be removed from the space 7o between the two cylinders. l l

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In a heating-stove, the combination,with the outer cylinder, C, provided with the escape-flue h and cold-air entrance c, of the inner concentric cylinder, B, having the escape-opening g diametrically opposite the flue h, and the flange c, extending from above the openings h g downward on each side and 8o below the opening c, dividing the annular space between the cylinders into a lower smoke-chamber and an upperhot-air chamber, the latter of which is provided with es-y cape-openings, substantially as herein shown and described. f p

2. The combination, in aheating-stove, of an inner and an outer cylinder, and the inclined iange or partition dividing the space between the two cylinders into a smoke-chamber anda hot-air chamber, the latter being provided with openings for the escape of the heated air, substantially as described.

3. In a heating-stove, the outer cylinder, C, formed with the enlarged top portion, d, in combination with the combustion-chamber B, provided with the opening g, and the flange e, dividing the space between the two cylinders into chambers f f, substantially as here. in shown and described.
